Automated swimming pool cleaner having an angled jet drive propulsion system

Abstract

A self-propelled cleaning apparatus for cleaning a submerged surface of a pool including a housing having an interior chamber, a plurality of supports rotationally mounted to a lower portion of the housing arranged to move the cleaning apparatus over the surface of the pool. At least one inlet and at least one outlet, and a filter and a water pump disposed in the interior chamber, the water pump configured to establish a flow path through the housing by drawing water and debris from the pool into the housing through the at least one inlet, directing water through the filter, and discharging filtered water out of the housing to the pool through the at least one outlet, wherein the at least one outlet is configured to direct a pressurized stream of water at an acute angle with respect to the surface over which the apparatus moves.

We claim: 
     
         1 - 20 . (canceled). 
     
     
         21 . A self-propelled cleaning apparatus for cleaning a submerged surface of a pool, comprising:
 a housing including an interior chamber;   a plurality of supports rotationally mounted to a lower portion of the housing arranged to move the cleaning apparatus over the submerged surface of the pool;   at least one inlet and at least one outlet;   at least one filter disposed in an interior of the housing; and   an electric water pump disposed in the interior of the housing, the water pump configured to establish a flow path through at least a portion of the housing by drawing water and debris from the pool into the housing through the at least one inlet, directing water through the at least one filter, and discharging filtered water out of the housing to the pool through the at least one outlet;   wherein the at least one outlet is configured to direct a pressurized stream of water at an acute angle with respect to the surface over which the apparatus moves.
